How can everyone say the Bears have no chance against the Packers?

Both games the Bears played against the Packers were extremely close, not to mention that this upcoming game is in Chicago. Aaron Rodgers was pretty well contained in both games. Sure he went off against the Falcons, but the Falcons have a sub par p defense anyway. People seem to forget how important defense really is. I'm not saying the Bears are gonna blow out the Pack. I'm merely saying that it should be a close game that either team can win.
